ELECTRIC SOCKET COVER AND SHADE HOLDER.

Application filed. December 15, 1922. Serial No. 607,024.

county, and State of New York, have in vented certain new and useful Improvements in Electric Socket Cover and Shade Holders, of which the following is a specification.

This invention relates to a combined electric socket cover and shade holder.

An object of the invention is to provide a simplified form of combined electric socket cover and shade holder whereby the insertion and removal oi the shade is effected without the use of clamping screws or other threaded setting member, and the parts so assembled to obviate wabbling and accidental disengagement of the parts.

Pursuant to my invention, the socket cover is provided with a depending flange portion and a split ring is coordinated with the socket cover to prevent possible wabbling of the split ring relative to the socket cover. The split ring is provided with a lowerly disposed, inwardly turned skirt portion serving as a groove for receiving the bead or neck of the shade. The split ring is also provided with a substantially cylindrical flange portion arranged when the split ring is positioned within the socket cover to en gage the inner face of the depending flange portion otthe socket cover, thereby preventing displacement of the split ring from the socket cover. The locking means between the split ring and the socket cover is preterably located on the split ring and the socket cover at their mutually engaging portion's, thereby insuring securement of the in-' terconnection or" the locking means. Further securement t thesplit ring within the socket coveris provided by the conical portion of the split ring disposed above its cylindrical flange portion, which conical portion when the split ring is locked to the socket cover is brought into engagement with the inner face of? the socket cover.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawings, in which Fig. 1 is a front elevation of a combined socket and shade holder embodying my invention; this figure also shows a shade ined liereins' Fig, 2 is a side elevation taken at right angles to the view of Fig. 1; F 3 is a detail side elevation of my shell member, the split ring being removed;

Fig. 4 is a detail side elevation of the spiral ring in normal position; i

"5is a detail side elevation of the spiral ring shownin a twisted'position, at

iording insertion therein or reinovalthere from ot the shade; and" Fig. 6 is a detail vertical, sectional elevation on an enlarged scale, showing a locking lug of the spiral ringat a position when Just moved out or looking relation with the locking opening in the shell. f 7 Referring to the drawings, the inventio comprises a shell 10 of suitable contour for enclosing the electrical socket 111 having any approved construction and provided with the usual switch key 12 or the usual chain extending through the opening 13 in the shell 10. Y i

The shell 10 at its lowerly part-14 embraces the spiral ring 15 and such lowerly part may be in the form of a flange provided with the spaced locking openings 16 for respectively receiving the'lockinglugs 17, respectively carried-by the spiral ring-15.

The spiral ring 15 is provided at its lowerly portion 18 with an inturned skirt portion 18 for embracing and retaining the suspending flange or neck 19 of a shade holder 20, of any approved style; t

To afford ready removal from and inseriion within the spiral ring 15 from' the socket shell 10, the spiral ring 15, see Figs. t and 5, is slitted as is indicated at21'to provide the end portions22, 28 which may be displaced relatively to one another as is indicated in F 5 by twisting the split ring 15 toaflordthe insertionon withdrawal of the shade 20. In the form of the split ring 15, as shown in Figs; 4; and 5, the suspending member 15 is provided with the upper conical portion 24 which conforms generally to and engages the inner face of the similarly conical portion 25, see Figs. '2 and 6, of the socket shell 10,

The shell 10 may be provided with the eye 26 or other suitable meansfor suspendingor aifixiug the combined socket shelland shade holder in position. 1

' A shade 201s inserted in position within the holder upon remoyal of the split' ring expanding the split ring 15, thereby enlargskirt portion 18 of the split ring 15 and the 15 from the socket shell 10. The removal of the split ring 15 is effected bymanually grasping its lowerly inturned skirt portion 18 of the suspending member 15 andturning the same to force the respective locking lugs 17 out of the'openings 16 of the socket shell 10 and then withdrawing the split ring 15 downwardly out of the socket shell 10. The

shade 20 is then inserted within the split ring 15 by twisting the suspension member 15 to the position as shown in Fig. 5, starting a portion of the'edge 19 of the shade 20 within the thus exposed edge 27 (see Fig. 5) of the groove, sayiat the-side 23, and

turning the shade 20 until-the fulledge19 of the shade 20' is seated within the groove ofthe skirtportion 18 of the split ring 15,

the split ring 15 while keeping the locking lugs 17 in register with'the openings 18, the,

locking lugs 17. enterqand become locked within there'spective'openings16.

To withdraw a shade20 from the split ring 15, manual pressure is applied to the split ring-15 isturned to withdraw the lugs 17 from the'respectiveopenings 16, as is indicated in Fig. .6; however, in figure 6, the

locking lugs 17 are not shown in fully dis-.

connected 'position. Thereafter, the split ring 15 is withdrawn; from the interior of the socket shell 10 and the shade I 20 is re-' leased from the split ring 15 by manually twisting the splitring 15 approximately to its shape shown-in Fig. 5 to cause the edge 7 19 of the shade 20 to clear the groove 28 of .the end portion 24 of the split ring 15, and

the shade 20 is then turned until its entire edge portion 19freedfrom the split ring 15. r If desired, the split ring 15 may be placed on the edge 190i the shade 20 by manually ing the effective diameter of the split ring 15 until its skirt portion 18 extendsabout the suspending edge 19 of the shade'2O and upon release. of such manual outward pull, the split-ring 15 engages theshade 20. Thesplit ring-"15 is then inserted within the socket shell 10 by manual turning of its skirt por tion 18,- as set forth hereinabove and the respectivelugs 17 positioned within thelocking openings 16. t

If desired, the shell or socket cover 10 and theisplit ring 1 5' may be formed of metal 1s1m1lar to shadejholders-heretofore proposed. The locking lugs 17 i may be formedby punching the material of the split ring 15, thereby-resulting inthe formation of the punching opening 29, as is indicated in Fig.

(3; I have discovered that such form of locking lug 17 is effectual by reason imparted to the "wedge-shape of the'resulting locking lug 17, in that the securement of the wedge of the lug 17 when in locking 7 position is" enhanced and the insertion and removal of the locking lug 17 within its locking opening 16 are facilitated. Simi larly, each opening 16may be formed within thesocket cover 10 by a punching operation,

thereby giving rise'to the-inwardly extending lugBO, see Fig. 6, whereby upon insertion of the spiral rings 15 within the 'socket cover 10 further lockingis attainedby the abut ment 30'of the" socket cover 10 entering the respective openings 29 of the .s lit ring 15.-

As is indicated, in :the drawlngs, the split ring 15 is shaped to have a central, substantially cylindrical flange portion 31, arranged when the split ring 15 is inserted within the socket coverlO to engage the inner face ofthe depending, substantially cylindrical flange portion 32, thus attaining enhanced rigidity of these parts of my combined socket cover and shade holder and preventing wobbling. 1 It will be observed that the interconnecting locking means- 16,17, are

respectively locatedin the mutually engaging, substantially cylindrical I flange ortions 32, 31 of the socket cover lOand o the split. ring 15,-thereby preventing accidental disconnection of the locking means.

Whereas I have described; my invention by reference to specific forms thereof it will beun'derstood thatmany changes and modifications may be made without departing from the spiritof the invention; I claim.
